You should find some literature from fluid mechanics, there are many
phenomenons in flow around cylinder (rod). For example boundary layer
(layer with lower velocity near the wall), flow stability (reynolds
number Re) etc.
I am working with corona discharge in flow (geometry wire-plate).
There could be strong ion wind there.
